Geometric Distribution Question

In the process of meiosis, a single parent diploid cell goes through eight different phases. However, only 60% of the processes pass the first six phases and only 40% pass all eight. Assume the results from each phase are independent.

(a) If the probability of a successful pass of each one of the first six phases is constant, what is the probability of a successful pass of a single one of these phases?

(b) If the probability of a successful pass of each one of the last two phases is constant, what is the probability of a successful pass of a single one of these phases?

I am not 100% sure this is a geometric distribution, but I am not sure how to set up the formula. Thanks for any help.

(a) If the probability of a successful pass of each one of the first six phases is , and the results are independent, then the probability that all six phases are passed is

(to 4 d.p.)

(b) If the probability of a successful pass of each one of the last two phases is , then the probability that both of these are passed is . So:
